Broadband speeds in CO6
Share of CO6 premises by the fastest download speed available, averaged across all 999 postcodes in the district.
Gigabit reaches 82.7% of postcodes, a solid figure, but superfast baseline drops to 90.4%, and 4.9% of postcodes fall below 10 Mbps. Wireless is exceptionally high at 37.2%, suggesting large swathes of CO6 rely entirely on wireless solutions, likely due to terrain or sparse rural settlement where cable trenching is impractical. One-third of postcodes depend on wireless, the rest on cable or fibre gigabit. This district presents a two-tier picture reflecting infrastructure choice rather than network failure. The high wireless proportion signals rural deployment economics: wireless backhaul reaches dispersed properties cost-effectively where fixed cable would require extensive trenching. Babergh's geography is not uniform; some sectors are cable-centric, whilst CO6 reflects investment in wireless solutions.
